By the end of 1969, the plant was producing its first beryllium hydroxide concentrate. Process for Refining Bertrandite Ore The solvent extraction process removes the beryllium by first crushing and wet grinding the ore in a ball mill, then leaching it with sulfuric acid and steam in rotating tanks at 95 ° C to dissolve the beryllium.
Treatment with acids, roasting with complex fluorides, and liquid-liquid extraction have all been employed to concentrate beryllium in the form of its hydroxide. The hydroxide is converted to fluoride via ammonium beryllium fluoride and then heated with magnesium to form elemental beryllium.
For 50 years, Materion and its predecessor companies have been leading suppliers of the beryllium industry's primary feedstock, high-quality beryllium hydroxide. Solutions of bertrandite and beryl are combined and processed through solvent extraction to concentrate the beryllium and remove impurities.

Beryllium hydroxide, Be (OH) 2, is an amphoteric hydroxide, dissolving in both acids and alkalis. Industrially, it is produced as a by-product in the extraction of beryllium metal from the ores beryl and bertrandite. The natural pure beryllium hydroxide is rare (in form of the mineral behoite, orthorhombic) or very rare (clinobehoite, monoclinic).
